Embodiment 1
[0024] The present embodiment provides a kind of processing technology of hemp fiber for seedling raising base cloth, and its technical process is as follows:
[0025] (1) Mechanical pretreatment: The raw hemp is repeatedly rolled 120 times by rollers to obtain rough hemp, and then washed with water to initially remove part of the hemicellulose and lignin attached to the fiber surface;
[0026] (2) Pre-soaking treatment: Soak the hemp obtained in step (1) in a peracetic acid pre-soaking treatment solution, wherein the concentration of peracetic acid is 4%, the temperature is 65° C., the pH value is 6, and the time is 65 minutes; Washing with water again after completing the presoaking process to obtain hemp fibers;
[0027] (3) Scouring: the hemp fiber obtained in step (2) is further scoured, and after scouring, first use 80°C hot water to rinse, and then use 20°C cold water to wash; wherein, the bath ratio of scouring is 1: 9. The scouring temperature is 60°C, the scouring t...
Embodiment 2
[0033] The present embodiment provides a kind of processing technology of hemp fiber for seedling raising base cloth, and its technical process is as follows:
[0034] (1) Mechanical pretreatment: The raw hemp is repeatedly rolled by rollers for 150 times to obtain rough hemp, and then washed with water to initially remove part of the hemicellulose and lignin attached to the fiber surface;
[0035] (2) Pre-soaking treatment: soak the hemp obtained in step (1) in a peracetic acid pre-soaking treatment solution, wherein the concentration of peracetic acid is 4%, the temperature is 70° C., the pH value is 7, and the time is 80 minutes; Washing with water again after completing the presoaking process to obtain hemp fibers;
[0036] (3) Scouring: the hemp fiber obtained in step (2) is further scoured, and after scouring, first use 90°C hot water to rinse, and then use 30°C cold water to wash; wherein, the bath ratio of scouring is 1: 12. The scouring temperature is 70°C, the scour...
Embodiment 3
[0043] The present embodiment provides a kind of processing technology of hemp fiber for seedling raising base cloth, and its technical process is as follows:
[0044] (1) Mechanical pretreatment: the raw hemp is repeatedly rolled by rollers for 180 times to obtain rough hemp, and then washed with water to initially remove part of the hemicellulose and lignin attached to the fiber surface;
[0045] (2) Pre-soaking treatment: soak the hemp obtained in step (1) in a peracetic acid pre-soaking treatment solution, wherein the concentration of peracetic acid is 5%, the temperature is 75° C., the pH value is 8, and the time is 90 minutes; Washing with water again after completing the presoaking process to obtain hemp fiber;
[0046] (3) Scouring: the hemp fiber obtained in step (2) is further scoured, and after scouring, first use 80-100°C hot water to wash, and then use 35°C cold water to wash; wherein, the bath ratio of scouring is 1:14, the scouring temperature is 80°C, the scou...
